Solar Energy Collecting: An Alternative Energy SourceAs a result of its gradual cost-effectiveness, alternative energy has become really popular in many areas of the world. That is why there are more solar panels on homes and business than in the past. The black squares on solar panels, known as solar cells, have become cheap and more efficient to use. Because of advancement in technology, these photovoltaic cells can collect the sun's energy in a smaller area. These solar cells have become very useful since they can now be manufactured at smaller sizes and at lower cost. In the last 20 years, the cost per watt to make solar energy has been cut down by 50%.
The great thing about solar energy that environmentalists like is that it produces no pollution. For other people, the fact that they can save a lot of money on their energy consumption with this source fo energy is the top reason. Because majority of people are more interested in money savings than the environment, it has taken the lowering of costs to get them to utilize solar power. Also setting these solar panels on your rooftop is now easy to do, which also helped in the rapid growth.
The way hot water is made is the water goes through an encasement of the solar cells, the water is heated then directed through the pipes. The cells have become clever enough to capture enough radiation from the sun even on sunless days. A company knowns as Uni-Solar has created solar collection arrays that can gather energy during severe weather. This technology is advanced where more energy can be stored during sunny days to make up for days when sunlight becomes limited. Another system of solar energy known as the PV System is available too. is hooked up to the electrical grid that is nearest, and transfers the excess energy to that grid for shared use. As a result, there is less ependence on major electrical plants and lower energy bills for the home.
So the main benefits of using the PV system is less dependence on the grid, decreasing pollution and bringing down energy costs. There is a growing trend in many towns and suburbs where they are installing their own centralized solar collection arrays. Evidence of solar energy becoming a legitimate energy source is its use in a lot of big companies. Google HQ is planning on installing a 1.6 megawatt solar power plant on its roof, and even Wal Mart has plans of its own 100-megawatt solar power system.
Governments are assisting the solar energy cause, with nations, including Germany, Japan, Switzerland and the United States, offering subsidies and tax benefits to individuals or business organizations for producing electrical power using solar energy. Investors also see the value in promoting green technology and will keep on investing money into it. As the use of solar power becomes more and more typical, the prices will continue to go down, which could only benefit everyone.
